I did a little searching, but couldn't find much of anything as to your specific question. My guess is that they aren't the same, but I don't know. Who knows, maybe the seats are different, but the fittings for securing them are the same, so they could work. Hard to tell, though, of course.
One thing I did find, though, is on car-part.com (I just recently found the site, myself - it looks to be pretty dang useful!) and it looks like there are quite a few somewhat less expensive possibilities there they you may be able to work with.
